Weights for catch and pull phase of swimming?

I’ve done some workouts using pullies…on my knees, reaching up to grab handle with one arm and trying to mimic the catch and pull phase of the stroke. I know that form and yardage are the biggest parts of going fast in the water but I would think that gaining shoulder and lat strength this way should help. Or am I waisting my time?

If nothing else, stretch cords are incredibly valuable … i’ve had good personal experience as have my athletes that stick w/ the program.

I would think they should have similar results. The only difference is that the stretch cords get harder toward the end of the stroke.

can’t really simulate resistance for swimming using weights, as momentum will likely prevent even application of resistance. i’d also advocate stretch cords, since they are easy to use. also it’s good that the resistance is harder at the end when using stretch cords, as that is where you want to apply a good chunk of your power. i use higher repetitions, between 30 and 50 reps of double arm pulls, depending the thickness of the cords i am using.
